EVGA kicked off its GeForce GTX 680 lineup with no less than five models. The Into, SC, FTW, Classified, and HydroCopper. Intro is the absolute base model, with fanatic adherence to NVIDIA reference clock speeds of 1006/1056/6000 MHz (core/boost/memory effective) and board design; SC (or SuperClocked) is a factory-overclocked model that has slightly higher clock speeds, and augments the NVIDIA reference design with an EVGA-exclusive backplate. Then there's FTW, which features a custom cooler design by EVGA, with even higher clock speeds than SC. The last air-cooled model is the Classified, which our sources tell us will have "astoundingly" high clock speeds. HydroCopper retains the clock profile of Classified, but replaces the cooling assembly with a Swiftech-built copper water-block. EVGA is yet to reveal the design of Classified, and the clock speeds of the factory-overclocked models. There are other variations, such as EVGA's "Signature" design with SuperClocked clock-profile, FTW with 4 GB memory, etc.
